Sometimes an author needs the proper atmosphere to write a novel. This could mean writing in the park or woods, the loud cityscape, or listening to the right music.
Sometimes listening to famously fantastical instrumental soundtracks like the music in “The Chronicles of Narnia” or even “The Pirates of the Caribbean” can be too distracting or subconsciously influence your writing style to match the films paired with the soundtracks. If you’re looking to write in a particular style this can be useful, but what if you’re trying to be unique? I’ve found individual YouTube artists and composers are the best way to discover inspirational music.
I personally enjoy artist and composer Adrian von Ziegler. His work ranges from Celtic to Nordic or viking, and encompasses the essence of fantasy. He himself is a fantasy writer who finds it useful to accompany his writing with compositions, so you know everything he records is original!
If Celtic and Nordic aren’t what you’re listening for, look at ThePrimeCronus, who collects songs from artists and orders them into hour long mixes. He describes everything with helpful titles like “Dawn of the Villains- 1 Hour of Powerful Dark Epic Music Mix” and “Spellborn [Epic Emotional Drama]”.
Also take a look at You Write Fiction‘s Top 10 Soundtracks for Writing Fantasy. These soundtracks are from various films and aren’t in any particular order, but if you’re searching (or listening) for inspiration this is a great place to start!
